does any one know what 2 wires the brake bulbs wire into on the tailight harness? i got a red and black on the brake bulbs and then the 4 wires on the harness that go to the turnsignals im kinda stumpped and cant find a good wiring diagram

 

On my 65, the green/orange and the black wire go to the back of the bulb.
So if your harness has the green/orange wire, that will probably go to your red wire, and the black to black.
